Problem Scenario
Broad Question
What melts ice the fastest?Specific Question
What liquid effects the melting rate of ice the fastest between orange juice, water, and soda?Hypothesis
I think that orange juice will be dominant because of the acid.Graph of Hypothesis
Variables
Independent Variable:
The liquid i change.Dependent Variable:
How fast the ice melts.Variables That Need To Be Controlled: of
Temp. , amount of ice, amount of liquid.Vocabulary List That Needs Explanation
General Plan
Freeze a temperature probe in a plastic cup and let it melt with the various liquids. let it melt and then use the logger lite program to graph my data. Also using mutable replicates of each liquid. Take the data and convert the graphs to raw data, then put it on my poster.Potential Problems And Solutions
The ice might be hollow.Safety Or Environmental Concerns
I could trip and fall on the soda can, get a concussion and have to go to the ER and end up in a coma ware they find i have to tumor and have less than a week to live and i have a really bad headache from the concussion and im out of chips so i walk out of the hospital and get hit by a mac truck die and the funeral was really bad cuz the coffin was too small and they had to cut of my legs with a hack saw so i fit and now im a ghost and m mad about it .Experimental Design
Number Of Trials:
2 for each.`
Number Of Subjects In Each trial:
2When data will be collected over
5 hoursNumber of Observations:
2 per minWhere will data be collected?:
logger liteResources and Budget Table
Data Table
Time Line
At the beginning of April i will start my experiment and have it completed by a later date in April then start my poster .Background Research
Ice freezes at 32 degrees F or 0 degrees C. The melting point s the same also. When ice freezes it expends when it melts it contrast. Hot water can also freeze faster than cold water.Molecules are constantly moving heat makes them move faster and cold makes them move slower the cooler it gets the molecules will end up sticking together to form ice crystals. water reaches its maximum density at about 4 degrees c..When water crystallizes it freezes by a open hexagonal form witch is larger than the waters original state.Water floats when frozen because it is less dense so it can float.
Scientist say that waters strange behavior is caused by the shape of its molecules , water is very unique when freezing.

Detailed Procedure
-I froze the water in the cup with the temperature probe 350 ml of water.-Then i put 10 ml of each liquid
-plug the probe in the computer collect the data for 5 hours taking 2 temperatures a min then take the graphs.

It started to melt and stopped at bout 94 mins and started again at 280 min to room temperature.
It rapidly melted at 130 mins.
It slowly melted at 79 mins.

Data Analysis
Orange juice came dominate at the most proficient way.Conclusion
OJ came in first soda 2nd and 3rd was water.Discussion
I found that the orange juice melts the ice the fastest. The acid probably helped a little.My data was messed up about 4 times because of electronic failure when my temp. probes failed. I tried to fuse the data together but it did not work.my experiment was not exact because if you use it outside it will probably freeze along with the ice.Benefit to Community and/or Science
If you run out of salt for your front step you could use household productsAbstract
What melts ice faster OJ, soda, water. orange juice should be dominant because of the acid. I researched how ice expands when frozen and war water freezes faster than cold water. I froze the temp. probe in a cup and plugged it into a computer and put in 10ml of each liquid. OJ was the best soda the 2nd and water the 3rd. so OJ was the faster. my hypothesis was correct .
